Reducing Rejection Rate by Applying Varying Parameters on Crankcase through Investment Casting Method

摘要

Casting industries suffer from poor quality and productivity due to large no. of defects. Investment Casting is one such type of casting method which can cast the material .Among different types of casting processes, Investment Casting is most widely used as it has significant advantages as compare with other casting processes. Earlier we were getting too much rejection on crankcase because of Shrinkage and porosity. This Research paper is based on how to reduce the rejection rate by applying varying parameters on crankcase through Investment Casting. To achieve the best possible solution we have conducted series of experiments by applying varying parameters like pressure, temperature, holding time etc. on Injection Moulding machine.
